Hi @Alex Kraemer 

You want to check if Affected Service Assigned to is Active?

If yes then your script simply do below

if(current.u_affected_service.assigned_to.active == true ||current.u_affected_service.assigned_to.active == 'true')

{

gs.eventQueue... //Add code here

}

else

{

alert('User is not active');

return false;

action.setRedirectURL(current);

}

Hope this helps

Thank you
Prasad
